Abstract

The valve seal fitting has a closing member (1) against which a radially projecting sealing element (3) is held in an annular groove (10). The sealing element is also against a valve seat (2) of larger diameter. The annular region has one or more overflow channels, possibly formed by radial U-shaped ribs (101). The sealing element is held with little axial movement against the sealing edge (11) on the closing member. There are one or more throttle channels (4) of smaller diameter than the overflow channels downstream of the sealing element.
